Quick links

Allow extra time to park, check bags, go through security and get to your gate
To help expedite your next trip through Sea-Tac Airport follow these Insider Tips and Tricks:
  • Arrive Early! Travelers are encouraged to arrive a minimum of two hours before domestic and three hours for international flights – give yourself time to park, check bags and get through security.
  • Peak hours can mean TSA checkpoint lines are longer. The busiest times typically are between 5 -11 a.m. Increased flights during the evening create another busy period between 7-9 p.m.
  • Thursday and Fridays are the busiest days during the week.
  • Pack Safe: know before you travel what items are and aren’t allowed in carry-ons and checked bags.
  • Print boarding passes ahead of time or use self-serve kiosks at ticketing.
  • Travelers can reach all gates from any TSA security checkpoint. The central checkpoint is open 24/7.
  • Empty liquids before you get into TSA lines.
  • At security checkpoints, have boarding pass and ID ready and remove laptops from their bags ahead of time.
  • Sign up for Trusted Traveler programs such as Pre-Check or Global Entry. These programs allow approved travelers to take specific designated lines for quicker service through checkpoints.
